The 40-second spot, which reveals a veiny and sinister-looking Electro attached to a large contraption, debuted as part of Comic-Con in San Diego, Calif. It ends with the words “Electro Arrives” and where the Spider-Man panel will be at the convention. More information about the film will be provided then.

“Amazing Spider-Man 2″ is slated to hit theaters on May 2, 2014. Comic-Con International kicks off today, and continues until Sunday.
